13. Which system of inequalities has no solution?

Mathematics
1 answer:
Anit [1.1K]3 years ago
8 0

Answer:

Option A

Step-by-step explanation:

We have y < 2x - 4 and y > 2x + 1.

=> 2x - 4 > 2x + 1

=> -4 > 1

Since this inequality is false for all real values of x, there is no solution for the system of inequalities.

2 parts compost, 6 parts potting soil for 10 kg of mix. How many kg of compost
likoan [24]

Answer:

Step-by-step explanation:

A proportion could be used.

With 2 parts of compost and 6 parts potting soil, you would end up with 8 total parts.

So it can be written as a ratio of compost to total mix, or \frac{2}{8}

The problem states 10 kg are needed in total, and the variable would be the amount of compost

As a ratio it would be \frac{x}{10}.

Use the ratios to write a proportion.

\frac{2}{8} = \frac{x}{10}

Multiply both sides of the equation by 10

\frac{20}{8} = x

Convert to a decimal if desired.

x=2.5

Solve for p.<br><br> 7+p+9=17<br><br> Enter your answer in the box.
Dovator [93]

First combine like terms.

7+9=16

16+p=17

Subtract 16 from both sides of the equation.

16-16+p=17-16

p=1

You can check to see if the solution is true by substituting 1 into the original equation.

7+1+9=17

17=17
